These systems use different forms of visualization to assist in understanding object-oriented applications. In particular, some VSs are designed to visualize programs written in the Java programming language (and they are often implemented in such a language, too). Java is an attractive language for visualization developers, because it is a ”comfortable” language and it is simple to build visualizations in Java. In the particular case of Java VSs implemented in Java itself, there is an additional advantage: the Java Virtual Machine provides an interface to debug programs written in Java, namely JPDA (JPDA). This interface avoids the need of using external debuggers or of generating program traces. The former often involves obscure interfaces; the latter requires to introduce additional code within the target program in order to extrac...

Nowadays, to manage, extend and correct web applications can be difficult due to the navigational paradigm they are based on. Hi!MVC framework helps to make these tasks easier. This framework allows building a web based interface, generating each page from the objects that represent its state. Every class to be showed in the interface is associated with two entities: its html representation (view) and its interactions in the view manager (controller). The whole html page is generated by composition of views according to the composition relationship of objects. Interactions between user and application are managed by the controller associated to the view which shows interaction elements (links or forms). Hi!MVC allows building web interface in a hierarchical and distributed way. There are other frameworks and APIs offering MVC architectures to web applications, but we thi...
An Evaluation of a Symbol Table Visualization Tool

A controlled experiment was conducted where pedagogical efficiency and the students’ opinion were evaluated. Students (n=45) were asked to answer three tests on symbol table concepts and a questionnaire on the tool. The evaluation indicates that SOTA fosters students to use it. They feel comfortable with it because they believe that: it has good quality, it is easy to use and useful, and it helps them in studying symbol table concepts. More importantly, SOTA facilitates learning, in the sense that it reinforces their trust in the knowledge acquired. Students who used the tool solved the problems correctly and significantly faster than students who did not use the tool.

The goal of the conference is to promote the exchange of relevant scientific and practical information between colleagues working on the same discipline. Furthermore, Koli Calling aims to combine practical teaching and learning experiences with solid research orientation. The conference is open for international computing education research (CER) community. Indeed, although held deep in the backyards of Finland, the meeting has gathered people from many countries from the very beginning. Over the years, it has developed into its present form of a rigorous scientific meeting and also gained more international visibility. Last year can be considered as the breakthrough of the conference, and this year we were able to keep up the continuous development in scientific quality and international impact. Today, the Koli Calling conference is well-established and recognized by the international CER community.

For these reasons, some frameworks are emerging which facilitate the inclusion of security processes (i.e. authentication and authorization) in a declarative way through aspect weaving. In this context, ACEGI is the reference framework being used today by thousands of large web applications. However, there is not such a framework when dealing with SIP/IMS development. In this direction, the objective of this paper is to present an extension of ACEGI, which enables developers a seamless use of this powerful framework for creating secured Java applications based on SIP. This approach has a number of advantages including the fact that authorization and authentication processes can be incorporated easily into SIP/IMS applications and that we can use the same security framework for developing convergent SIP/Web secured applications without the need of duplicating the security code.
